My normal process is to fly around until I find a greater dragon and cast invisibility on myself. While I am invisible I will animal lore it. Without sounding critical, because I am not, is the 6 seconds something that will be present on the release version or should it be able to evaluate an animal much quicker in the future?
Unfortunately, 6 seconds is kinda the normal considering the way EUO does character recognition. You'll find that it's not a big deal once you play with it, especially if you have invisible going. You basically can't really read it faster anyhow, let alone doing any computation.
Having said that, I know EUO is considering doing things differently when it comes to gump information. If they do go through with making gump info available to the normal scripter, then eval gumps can be considered much faster.
For the time being, we are stuck with what EUO gives us to work with.
As it stands, many gump-related EUO scripts can take a bit of getting used to. You might have to adjust your playing timing, and know that if things are happening around you, they might affect the way scripts work (such as damage_numbers being spammed). These are the fleas of this particular dog.
